Demonstration of regulatory cross-talk between P fimbriae and type 1 fimbriae in uropathogenic Escherichia coli [PDF]
Microbiology, 2006 The majority ofEscherichia colistrains isolated from urinary tract infections have the potential to express multiple fimbriae. Two of the most common fimbrial adhesins are type 1 fimbriae and pyelonephritis-associated pili (Pap). Previous research has shown that induced, plasmid-based expression of a Pap regulator,papB, and its close homologues can ...

Purification and Characterization of Type 1 Fimbriae of Salmonella typhi [PDF]
Microbiology and Immunology, 1994 AbstractType 1 fimbriae have been purified from a Salmonella typhi strain of clinical origin. Purified fimbriae retained their ability to bind to erythrocytes in a mannose‐inhibitable fashion and, in doing so, behaved preferentially as a monovalent adhesin.

Strain and host-cell dependent role of type-1 fimbriae in the adherence phenotype of super-shed Escherichia coli O157:H7 [PDF]
International Journal of Medical Microbiology, 2021 Super-shed (SS) Escherichia coli O157 (E. coli O157) demonstrate a strong, aggregative, locus of enterocyte effacement (LEE)-independent adherence phenotype on bovine recto-anal junction squamous epithelial (RSE) cells, and harbor polymorphisms in non ...

RstAB activates type 1 fimbriae to promote uropathogenic Escherichia coli bladder invasion [PDF]
iScienceSummary: Urinary tract infections (UTIs), primarily caused by uropathogenic Escherichia coli (UPEC), are a significant public health problem. UPEC relies on type 1 fimbria to invade bladder epithelial cells (BECs), which is a crucial step in the ...

Lrp acts as both a positive and negative regulator for type 1 fimbriae production in Salmonella enterica serovar Typhimurium. [PDF]
PLoS ONE, 2011 Leucine-responsive regulatory protein (Lrp) is known to be an indirect activator of type 1 fimbriae synthesis in Salmonella enterica serovar Typhimurium via direct regulation of FimZ, a direct positive regulator for type 1 fimbriae production.

Arginine within a specific motif near the N‐terminal of FimY is critical for the maximal production of type 1 fimbriae in Salmonella enterica serovar Typhimurium [PDF]
MicrobiologyOpen, 2019 An important Salmonella serovar for both human and animals Salmonella Typhimurium possesses 13 gene clusters that have the potential to produce fimbrial structure, among which the type 1 fimbriae with the binding specificity to mannose residue is the ...

Porphyromonas gingivalis fimbriae
Journal of Oral Microbiology, 2013 Marginal periodontitis is not a homogeneous disease but is rather influenced by an intricate set of host susceptibility differences as well as diversities in virulence among the harbored organisms. It is likely that clonal heterogeneity of subpopulations
